I'm looking for a way to listen to podcasts at 2x on my iPod classic. I know this is not supported out of the box.
Is there an alternative firmware like rockbox, that supports syncing with iTunes and double playback speed or - which I assume is likelier - a Mac app that allows me to easily speed up the mp3 files. With easily I mean it should support editing in batch and replacing the files automatically, ideally started with a script directly in iTunes.
(I do know about audacity, but I want something a little more automated)
